Authorities in Florida gave up the search Saturday for a man presumed dead after a sinkhole opened beneath the bedroom of his family's suburban Tampa home, swallowing him up.

The effort to recover the body of Jeff Bush had resumed earlier in the day after authorities stopped operations overnight, saying the hole was still expanding and the house could collapse at any time.

"We just have not been able to locate Mr. Bush and so for that reason the rescue effort is being discontinued," Mike Merrill, county administrator for Hillsborough County, told reporters Saturday evening. "At this point, it's really not possible to recover the body."

The research engineer's rising career seemed enviable. Shane Todd of Montana was working abroad in Singapore on the latest cell phone and radar technology, coveted by global corporations.

Todd was found dead at age 31, however, in his Singapore apartment last June, and his death has become an international controversy that involves local police, the FBI, an independent forensic analysis and, the parents allege, corporate intrigue found on their son's hard drive.

Singapore police have been investigating Todd's death as a suicide by hanging. They refer to a pulley system around a toilet and over a door in Todd's flat.

Secretary of State John Kerry arrived in Cairo at a critical stage as political divisions are preventing crucial economic reform.

In an intense 24-hours on the ground, Kerry has a packed schedule of meetings with Egypt's political and military leadership, business leaders and non-governmental organizations.

"It is very important to the new Egypt for there to be a firm economic foundation on which the new Egypt can operate. It will be important for the government to make an agreement with the [International Monetary Fund]," explains a senior State Department official who briefed reporters on Kerry's plane as he flew from Ankara, Turkey, to Cairo.

Egypt's ability to stabilize extends beyond its needs from the IMF, the official said. "It unlocks a lot of the other money that would come from the U.S., the EU, from the Arab states and also from private investment."

Necessary reforms include increasing tax revenue and reducing energy subsidies, U.S. officials say. But in order to carry out the kind of reforms required for getting IMF money, the official says, "there has to be a basic political agreement among all of the various players in Egypt."

The Obama administration has been stressing to President Mohamed Morsy the importance of political consensus. But not only does Morsy need to build consensus, administration officials say, the various political leadership in Egypt needs to participate, as well.

Kerry, the official says, will not call on the opposition to renounce their boycott of upcoming elections, but he will make clear "If they want to engage, if they want to ensure that their views are taken into account, the only way to do that is to participate."

Russia's foreign minister said Saturday it was concerned by a Texas coroner's report declaring the death of an adopted boy from the nation as accidental.
The 3-year-old lived in Texas with his adoptive parents.
The announcement of the accidental death came after an autopsy was completed on the boy, Max Shatto.
The foreign ministry said it did not receive the information on cause of death from U.S. officials, but from the media.

The shaka sign - a person's thumb and pinkie extended, the rest of the fingers in a fist - is uniquely Hawaiian, a way to say "right on," "hang loose" or simply hello.

But it turns out it's not the only way islanders have used their hands to communicate.

A research group at the University of Hawaii at Manoa announced Friday that they had documented - for the first time - Hawaii Sign Language, or HSL, which deaf people across the islands' diverse ethnic groups have used for decades if not longer.

While there is written evidence dating back to 1821 indicating such a language existed, beginning in the 1940s it started to get largely phased out in favor of American Sign Language.

Venezuelan President Hugo Chavez is "fighting for his life," the country's vice president said late Friday.
Chavez began chemotherapy after his fourth cancer surgery in Cuba in December, Vice President Nicolas Maduro revealed for the first time, and is continuing the "intense" treatment at a military hospital in Caracas.
